Use the Payment Content Block

Sell stuff directly on your landing page with the Payment content block. The Payment block syncs items from your Square account to your Mailchimp account. Use it to help visitors buy an item with a credit or debit card, without having to leave your landing page.

In this article, you’ll learn how to add a Payment content block to your landing page, and customize its styles and settings.

Before You Start

Here are some things to know before you begin this process.

  • Payment blocks are only available for landing pages and you can only use one Payment block per landing page. Make sure you’re familiar with Landing Pages in Mailchimp.
  • To sell things on your landing page with the Payment block, you’ll need to connect Square to Mailchimp. If you don’t have a Square account, set one up here.
  • Buyers from your landing page will be added to the Mailchimp list associated with your Square integration. Buyers who haven't opted in to marketing emails will appear in your list as non-subscribed contacts, and can receive transactional emails or social ads.
  • The payment content block is not available if you have a connected Shopify store.

How It Works

Add a payment content block to any landing page template at no additional cost. We include the block by default in the Promote Products and Accept Payments templates.


In the block, you can browse and choose an item in your Square account. Because you can only choose one item in the Payment block, it works best for items that do not have variants. For example, a product with variants is a t-shirt that comes in Small, Medium, and Large.

If you want to add any additional items to your store to sell on your landing pages, or change the price of an item, you’ll do that in your Square account.

When visitors decide to buy and click the checkout button, they’ll see a checkout form on your landing page.


After they complete the checkout form, Mailchimp will send them a receipt.


  • We recommend you include your preferred business contact information on your landing page in case buyers have a question or need help.

About Shipping and Sales Tax

Before you begin, make a note of the sales tax and shipping rates for the item you want to sell. Our Payment content block does not add sales tax or shipping charges to your item unless you enter them in Mailchimp first.

After you add a Payment content block to your page and and select an item from your store, you’ll need to enter the correct rates in the shipping and sales tax fields. We’ll apply these charges to the total cost of the item at checkout.


If your Square account lists the sales tax as part of the item price, you’ll still need to enter your sales tax rate in the Payment content block in Mailchimp.
